The Silk Leaf, by RCA graduate Julian Melchiorri, is the first manmade material that can perform photosynthesis. It has huge implications for science and technology and it could also make long-distance space travel a possibility.

One such holy grail quest of bio-inspired design is the development of artificial photosynthesis (AP).

As a punishing drought continues to grip California and other areas, scientists are exploring hardy succulents as a pathway to genetically engineer plants to use less water. Agave and other succulents such as the prickly pear, pineapple and vanilla have evolved to perform a different kind of photosynthesis that enable their survival in semiarid environments. These species absorb most of their carbon dioxide at night rather than during the day, as most plants do, meaning less water evaporates off the leaves through transpiration. 

Scientists are still trying to unravel the damaging effects of ground-level ozone on life on earth. But as the world warms, their concerns about the impact of this highly toxic, pollution-caused gas are growing.
